NITED STATES PATENT OFFICE@ CHARLES G. HERBERT, OF NEW YORK, N. Y.

CAMP-STOOL.

Specification forming part of Letters Patent No. 52,4l2, dated February6, 1866.

To all whom it 'may concern:

Be it known that I, CHARLES G. HERBERT, of the city and State ot' NewYork, have invented, made, and applied to use a certain new and usefulImprovementin Camp or Portable Stools; andl do hereby declare thefollowing to be at'ull, clear, and 'exact description of the saidinvent-ion, reference being had to the annexed drawings, making part otthis specification, wherein- Figure 1 is a side elevation of my improvedstool as open. Fig. 2 shows a portion of the camp-stool closed, the legsbeing partially in section, and Fig. 3 is asection of one of the legsdetached and shortened by'slidin-g the parts together.

Similar marks of reference denote the same parts.

My invention relates to a camp or portable stool ijttedl so as to betaken apart and rolled into a small compass for the convenience oftransportation.

Said invention consists in an extension-leg formed by a pipe containing'a sliding rod or tube, and combined with a cross-bar'that holds theseparate legs in their extended condition and connects four of saidextension-legs to form the camp-stool frame; and in combinationtherewith I employ a seat formed of Webbing, or similar material,attached to crossrails that set into notches at the ends ot' the ln thedrawings, a is a tube of suitable size and material. I prefer that itshould be iron or brass, about seven-eighths of an inch in diameter.Within this tube is rod or tube b, which I prefer to be made ot' woodand fitted loosely into the tube a. The tube a is perforated near oneend, and the rod b near the other. The rod can be slidden into the tube,as in Fig. 3, so as to occupy but little space in transportation, or itmay be slidden out until the respective holes coincide for the passageof the round metal end piece of the cross-bar c, as seen in Figs. 1 and2.

It will now be understood that all four of the legs of my camp-stool aremade as before described, and that they are set together in pairs at theends ot' the cross-bar c to form the donble X-legs; and to prevent thecross-bar o turning I provide a pin or key at l, Fig. 2, entering anotch or hole in the pipe a; and to keep the outer legs from slippingoft` the ends ofthe bar c, I employ lugs at 2 2, the pipe a at the holebeing provided with notches for passing said lugs previous to the legsbeing turned on c to position. Thereby the lugs come on the unnotchededges of the hole in a. The ends ot' the tubes a are slotted or mortisedto receive the rail-pieces ald, to which the webbing or seat e isattached. The ends ot' the tubes a pass into cavities in the under sideof the T-head of these. rail-pieces, and the lower edges ot saidrail-pieces are also notched to receive the bottom ot' the slot in thepipe a.. By this means the parts are prevented from moving'.

What I claim, and desire to secure by Letters Patent, is-

1. The extension-legs formed ot' pipes containing sliding' rods ortubes, in combination with the cross-bar that connects the legs andkeeps them extended, as and for the purposes set forth.

2. In combination with such legs and crossbar, the cross-rails and seat,itted substantially as specified.

In witness whereof I have hereunto set my signature this 8th day ofJanuary, A. D. 1866.

CHARLES Gr. HERBERT.
